gps update issue

I have a issue with my 1030 plus (SN: 6ET242580) with software version 6.75. The unit has stopped working and the was constantly updating the GPS firmware. When it restarted it couldn't find the maps.

I have tried resetting it, connecting to my computer and removing the folders of /new files and RemoteSW as recommended for the Garmin 830 with a similar issue.

Now I can't seem to acquire any satellites, and the unit is still not working

I would appreciate any advice

regards,

Lachlan
